Mastersound Dueventi-Plus Multiple Upgraded Tubes

The Dueventi is a parallel single-ended Class A integrated amplifier.  I bought this as a light-used unit and it is in great condition and i cannot find a single scratch on it.  It performs perfectly, is very quiet in operation and sounds excellent.  
Comes with tube cage that is unassembled and never used because i like looking at the awesome tube glow from the EL 34 tubes. To my ears this is what a tube amp should sound like and any spreaders 86db and higher will shine with this amp. The transformers are massive and swing large anoints of current. 
This is Mastersound’s best seller with positive reviews around the world.  My version includes triode/ultralinear modes and a very good MM phono stage.  Mastersound is well known for the quality of their transformers and you can hear why when you listen to this amp. Their uppermost, world-class level amps also operate parallel single-ended Class A and it's a proven, accomplished design.

The amp will ship with the original EH tubes.  If you're interested in the pictured quad of vintage Teslas or a set of vintage 12AU7s they are available.  Even with the EH tubes I think you will be very pleased with the sound of this amp.  Seek out the reviews of this version.

  I've never unpacked the cover so I borrowed the picture from the web to show you what it looks like.  Manual is a PDF print version.

Here is Mastersound’s write up:

"The Dueventi is an integrated amplifier in pure class “A” which enhances the technical evolution of the classic pentode EL 34. The output transformer we designed and manufactured for this pentode allows us to reach a range of extension which would be otherwise impossible with standard output transformers.  The result is a perfect sound stage and outstanding presence."
